The variable scale cutting control system based on PLC;

The application of the series of FX2N PLC in the numerical control cutting line was proposed in this paper,and by using frequency conversion 、sensor、and the series of MR-J2 servo motor it realizes the high precision variable scale cutting of silicon steel and puts emphasis on the organization process of F940GOT.

Aiming at six parameters(κ,γ,δ,μ,η and C_0) of the dynamic vibration absorber in deep sea,the optimal design of parameters was processed with Broyden-Flether-Goldfarb-Shanno(BFGS) method of variable metric method,penalty function method and the line-search method.

In this paper, we combine the extended projection type method given in 1 and uncontrained variable metric methodaand and give a new algorithm with n+m +1 parameters to solve linearly constrained nonlinear programming problems.

This paper prestents a class of reduced variable metric algorithm for programming problems with standard linear constraints with the help of reduced gradient and Huang s variable metric methods.

According to the problem of artillery control system and simulated annealing algorithm,a new improved simulated annealing algorithm,a simulated annealing algorithm based DFP is designed,and it is applied to PID control of artillery control system.

Adaptive method and variable scale method are introduced in this paper.

Variable scale method,a sort of optimal method,is used in design of optical system,meanwhile,the technique of using the ‘escape function’ for variable scale method in design is describle.
